Having problems with your BMW 525 ?

I have replaced the altenator and the battery and am still waking up to a car with a drained battery. there is a power drain coming from some where and has been to three different auto mechanics who specialize in BMW's and nobody can find the answer. BMW is going to charge me 4x the real cost of the problem so this is my last hope with you.

Answers :

CHANGE THE STARTER, WE HAVE TO LOOK AT THE PARTS THAT R CONNECTED DIRECTLY TO THE BATTERY AND COULD DRAW ENOUGH CURRENT OVERTIME IS THE STARTER OR LEVELING SYSTEM. CHECK ALL COMPONENTS WITH DIRECT BATTERY CONNECTION THAT R FUSED AT 40AMPS OR GREATER. AND USE THE PROCESS OF ELIMINATION OF THE MOST USED PART. THE STARTER CAN START THE CAR BUT ALSO IT IS POSSIBLE FOR IT TO DRAW CURRENT ONCE THE IGNITION IS TURNED OFF. USE A DIGITAL VOLT METER ON THE BATTERY TO MEASURE HOW FAST THE BATTERY VOLTAGE IS DROPING OVER TIME.
